Sit up straight

Are you sitting at a desk in front of a screen right now? Take note of what your back is doing. Are you hunched over? Are your shoulders rounded?

Poor posture can cause back pain and fatigue. Check out these other common posture mistakes and fixes from the National Health Service UK.
